As part of a fountian display, two jets of water from the surface of an upper pool and meet at the surface of a lower pool, as shown in the diagram. The paths of the two jets are modelled by y= -x^2-4x and y= 3x^2-15x, where x and y are measured in feet. what is the vertical height difference,d, of the pools? Round the answer to the nearest hundreth

A partial solution to the equation [ax+b]=cx+d
line 1 [ax+b]= cx+d
line 2 -ax-b= cx+d
line 3 (-a-c)x= d+b
line 4 x= d+b/-a-c for x less than or equal to -b/a
the first error recorded is a. 1
b. 2
c. 3
d. 4

if the graph of y= f(x), xER is the same as y= [f(x)], xER, then
a. f(x) may be of the form ax+b, a cannot equal to zero or of the form ax2+bx+c, a cannot equal to 0
b. f(x) may be of the form ax+b, a cannot equal to 0, but cannot be of the form ax2+ bx+c, a cannot euqal to zero
c. f(x) may be of the form ax2+bx+c, a cannot equal to 0, but cannot be of the form ax+b, a cannot equal to 0
d. f(x) cannot be of the form ax+b+c, a cannot equal to 0 or ax2+bx+c, a cannot equal to 0
